VALVE.

Ll-l fllfillh- Specification 01 Letters Patent. P tmm p 1 1914 Application tiled December 23,1913.

To all whom it may concern Be it known that I, J oszcrn G. l Soulnue, :1 citizen of the United States, residing at the city of New York. in the borough of Manhattan and Stlite oihNew York, have in vented certain new and useful Improvements in Valves, of which the following is a full, clear, and exactdescription.

This invention relates to velvet; and has special reference to rubber ball valves; which are used to control the outlet from flush tanks. This style of valve ordinarily consists of a hollow rubber ball linving o honii spheriral lower hull. and n srnnewlmt l'lultened upper half terminating in n net-h or nipple on its: vertiCnl axis. The, hall is carried at; the end of n vert'irol rod that iltlr'i tffw' into and engages with the nipple whereoy the bull may he raised and loworer'l to .llNl from its valve S'Hlli, the soot being formed at the open, end of a pipe of romporntivelr large diameter through which the ronteuts; of the tank l'lowu when the ball in lil'ted. These hall valves are i-l'ubjerted to various strains when in use whioh twonl'uully rouse their doFtruotion in the opernlion of the Volvo. When, it udjuoted to its ('loSoll po silion', the hall is subjected to a motion whit-h tends to elongate it: the u'iovemonlj oi the bull ugzzuufit its heat. is more or violent: the pressure of the body of "'llllOl' in the lord; on top of the bull tends to l'orrre ll. through the open end ol the outlet pipe and to distort? the upper l 'lll n 1' oi, the hull: the lute: movements of the stem muse the bent ling of the nook or nipple of the valve to whioo the stem is ntlnohed.

All oi. these ell-nine. as stated, eventually result in the (lLHiI'llt'llUll or iocalpnrity or" the bull and it is the objet't of HIV invention to provide u ooimtruotion of bull vulve whirh will resist these strains null will therefore he of lon ror lile than the orduun-y bull valve.

Aroordingglv, nrv invention consists in pro riding n rigid ongo within the interior oi the ball, which Page oonoists ol a. horizontal ring attached to the inner wall of the hull at or about ite middle and rigidly connected hv moons of inclined arms to vertically and dinmotri -nllr arrange-d hubs which are meolnmiroilr niltlltl'lll'l'l resrujsrlively lo the up per and lower ventral points of the bell. ll'v uzem'z of Fllflll n wage the walls of the bull are suste' led :weinst vertical oontrzurlion or Serial No. 806,324.

elongation us well as against horizontal contrnctien or extension, while the portions of.

the wall, which contort with the valve sent, are pernlitted to have their full flexibility and sealing qualities.

The invention will be described in detail in connection with the ing in whicl1-- l igure 1 is n verti rel central section of the innzrovod hull valve; Fig. 2 is a horizontal net-lion on line .:r--:r of Fig. 1; Fig. 3 is a plan of one of the reinforcing ports; and Fig. --lis; n deteilof o. part of the horizontal ring.

The hall 1 in of rubber and of any of the usual shapes ordinarily having; 1: semi-circular lower hnii, which engages with the valve sent and n more or lers flattened upper half having a ventral vertical neck" (-I' nipple 2. Thin nipple usually contains n metallio spud 3, having it vertical control threaded net-ouuuinying draw posnuge into which in oorewed the end of the rod 4, whiehserves-us the valve stem by which it is ruined and lowered. The valve seat s an inelined curved surlaee 5 formed nt the mouth or upper end of a passage 6 through whioh the water rushes when the ball is lifted. Tunide of this hall I place a supporting: more consisting of :1 horizontal ring; i sets ol. inclined arms and 9, the spud 3 and the their ornnt to. The ring 7 is leveled at: the horizontal substantially central plane of the bell and is preferably secured to the wall oi the bull in the process oi melting the letter, the rubber material being formed or permitted to flow around the outer edge and l'eeot; of the ring and into perforations 11, shown in Fig. 4. The arms 8 may be three or more in. number and are serured at their lower rude at equal distances apart. to the ring; 7'. From the ring the arms bend inward, preferably out of contact with the wall of the bull and ore secured to the spud 53. The spud 3 l5 lirmlv uni-bored in the net-l: or nipple E3 of the hull bv'helug: molded and 'l'ulcunizel'l therein. The set of urmn 5) are likewise attached to the ring 7, preferably in it stnsrgered relation with the arms 8 and are int-lined inward and downwind out of ronturt with the lower half of the wall ol. the bull illnl enter and are F0- cured to the smell disk or not Ill. The nut I!) is lrrntorl, some {ilsl'nnrt hovo the bo tom (it the bell end the bull is: provided with u into the nut. v

The post carries onits outer or lowerend, a rigidly attached curved disk 14: shapedto fit the outer surface of the ball, the cat being screwed into'the nut until the iak rests a ainst the ball. adjust this dis and post in position the disk is provided with two holes 15 on opposite. sides of its center for insertion o a spanner wrench. It will be seen that the cage thusformed together with the disk 14: furnishes a rigid support for the walls of the ball which resists all of the strains to which the ball would ordinaril be subjected in use. The elongation which tends to be produced by the suction in the passage 6 when the ball is seated is preventedby the 25. up'on the side Walls is therefore avoidedi fact that the lower portion of the ball rests upon the disk 14 and that in turn is sustained by the cage and the stem 4.

When the valve is thrown against its seat the lower wall is permitted to move upward as shown in dotted lines and the strain As soon as the valve is seated the wall drops back to its normal position. Lateral movement of the stem 4 cannot result in any tilting or bending of the neck 2 with respect to the bod of the ball, because such strains would e imparted to the cage and the bending thereby resisted. The downward pressure of the body of water on top of the ball which would have the tendency to crush the ball or to drive the neckdownward is resisted by the upper half of the cage. Any lateral pressures around the horizontal diameterof the ball are resisted by the ring.

The cage is inserted in the ball during the process or manufacture, the ball being made in two pie ces of similar shape to the cover of a baseball, which are placed in the mold surrounding the cage and while the rubber substance is in a plastic condition it is In drder to ftached, which hubs and the rin valve of an internal reinforcement therefor consisting of a ring having inclined arms extending therefrom above and below and two hubs arranged respectively above and below the ring to which said arms are atchanically attached to the wall 0 the hall.

2; The combination with a hollow ball valve and a rigid cage located inside of the same, said cage being mechanically connectannular line in a plane at right angles to the-line connecting said two points.

3. The combinationovith a hollow ball valve having flexible walls and a rigid-internal support thcr'efor, said support com-' prising a nut, and an external support comprising a disk provided with a screw for connecting it with said nut, the nut and disk ing from said rigid support to the .outsideof said ball valve,a disk attached to the outer" end of said post, and the wall of the ball valve having an orifice of greater diameter than that of the post through which the" wall will have free post passes whereby the play along the post.

In witness whereof I subscribe my Sig-f nature, in the presence of two Witnesses.
